FLUSH-TANK.

SPECIFICATION fo ming part of Letters Patent No. 685,406, dated- October 29, 1901.

- Application filed Pebiuary 12} 1900. Serial No. 4,969. (No model.)

is to be secured; and the object of the invention is to so form the tank and to so construct and arrange the mechanism therein that the tank may be concealed in most part in the wall of the bath-room with only a small portion thereof projecting.

A further object of the invention is to provide a construction in which separate floats will be employed for opening and closing the water-supply and for closing the water-outlet.

In the drawings forming a portion of this specification, and in which similar numerals of reference designate like and corresponding parts in the several views, Figure 1 is a View showing the tank'with a side removed and illustrating the mechanism therein, a

tank being formed in any suitable manner,-

but preferably of cast-iron, with a movable plate 7 upon the upper face of the base 5 to tom-of the tank and is provided with a com mon form of valve 10, adapted to be raised to permit the water to flow into the tank and to be lowered to cut off the flow of water, the water-supply from this valve to the tank being passed directly through a discharge-spout 11. For operating this valve mechanism 10 a lever 11 is suitably fulcrumed, as shown at 12, and has'one end connected with the valve mechanism 10, while an upright'rod 13 is connected with the other end and supports a hollow ball or other form of float 14, which lies in the upwardly-extending portionl6 of the tank. When this float is raised un der the influence of the body of water in the tank, the valve 10 is lowered and the supply of wateris cut oif. When the water is withdrawn from the tank, the ball 14 drops and the valve 1 i i 10 is raised to open the supply-pipe, when the .water passes through the spout 11 andi'nto the tank.

A flush-pipe 15 has an arm 16, which is ex- In order to close the flush-pipe to maintain a body of water in the tank, a valve 18is provided, this valve being shaped to fit closely andeasily into the seat 17 and form aplug therefor. The valve or plug 18 has a stem 19, through the medium of which it is slidably mounted upon an arm 20, extending radially from a shaft 21, which is journaled in the side of the tank and in a bearing-block '22 therein, this shaft 21 being passed exteriorly of the tank and having a lever 23 at its outer end, which may be operated to rotate the shaft in one direction and raise the plug from its seat. This lever 23 has an opcrating-handle 24 at one end to operate the shaft and raise the plug, and when the handle is released the weight 25 at the opposite end of the lever turns the shaft 21 and reseats the plug 18 in its seat 17.

It is of course necessary to provide some means for holdingthe plug raised to permit the entire contents of the tank to pass out through the flush-pipe, and for this purpose the shaft 25 has a second radially-extending arm 26, which projects upwardly and into the tank and is adapted for engagement by a latch 27. This latch is in the form of a lever pivoted between cars 28, attached to the top of the projecting portion 7 of the tank, and one end of this lever is weighted or enlarged to form a head 29, which holds the lever norof this head 29 is are-shaped, as shown, and

It 1 a this face lies in the path of upward movement of the finger or arm 26, so that as the arm is moved upwardly it will engage this arc-shaped face and will press the lever upwardly until it has passed beyond the head, when the lever will drop and the head will engage the arm to hold it in its raised position and with the plug 18 out of the seat 17. Upon the opposite end of the lever 27 from the head 29 there rests one end of a pivoted lever 30, which is adapted for movement to press the adjacent end of the lever 27 downwardly and move the head 29 upwardly from engagement with the arm 26 to permit the shaft 21 to turn and reseat the plug, the reseating of the plug being assisted by the column of water discharged from the spout 11 against the flat adjacent side of the plug.

In order to operate the lever 30 to reseat the plug after the contents of the tank have passed off, a lever 31 has one end engaged with the under face of the lever 30 at the opposite end from the lever 27, and upon the opposite end of the lever 31 is mounted a float 32, which may be in the form of a hollow ball, as indicated.

The operation of this construction is as follows: Supposing the tank to be full of water, the levers 27, 30, and 31, as also the float 32, the valve 10, and its connected'parts, will be in the same position as shown in Fig. 1 of the drawings. If the lever 23 then be operated, the arms 20 and 26 will be raised, when the plug 18 will be moved from the seat 17, and the arm 26 after engaging the head 29 of-the lever 27 will move the head upwardly and will pass behind the head, when the head will drop and all the parts will be in the position shown in Fig. 1. The water in the tank then runs through the arm 16 to the drain orflush pipe 15 and drains the tank. When the water in the tank drops to the proper point, the float 14 will move downwardly and will operate the lever 11 to open the valve 10. This opening ply-pipe to run into the tank, but at a, lesser rate than the outflow, so that the level of the water in the tank continues to drop. After the level of the water has reached the float 32 the continued drain of water lowers this float, when the lever 31 operates the lever 30, which in turn operates the latch-lever to trip it and release the arm 26 and permit the plug 18 to fall. The engaging face of the plug 18, however, is spheroidal, so that the rush of water through the seat 17 acts to force the plug away from its seat, so that the plug does not engage its seat until the entire contents of the tank are drained away. The plug then enters the seat to close the flush-pipe, and the level of the water in the tank gradually rises. As the water rises it raises the float 32 to permit the engagement of the arm with the latch at the next operation of the crank 23, after which the water reaches the float 14 and moves it upwardly to close the valve 10. Should the valve 10 not be closed completely, the excess of water may pass outwardly through an overflow-pipe 35, which is con nected with a flush-pipe 15, as illustrated.

It will of course be understood that in prac' tice the flush-tank may be made of any suit able material and that the upwardly-extending portion may have any suitable cross-sectional outline, it being only necessary that it only have such a depth as not to project be yond the face of the wall.

What is claimed is-- 1. A flush-tank comprising an enlarged lower portion and an upwardly-extending and reduced portion, a supply-pipe communicating with the tank, a valve mechanism for the supply-pipe located in the lower enlarged portion of the tank, a float for operating said valve mechanism and located in the upper reduced portion of the tank, a drain-pipe leading from the base of the tank, a shaft passed into the bottom of the tank, a valve for the drain pipe carried by said shaft, a latch mechanism for holding the valve in raised position, and a float within the lower portion of the tank and adapted to operate the latch to release the valve.
